IMPACT WATER-WHEEL.

Specification of Letters Patent No. 11,296, dated July 11, 1854.

To all whom t may concern.'

Be it known that I, ABEL GREENLEAF, of Kingston, in the county of Luzerne and State of Pennsylvania, have invented certain Improvements in Gravity and Percussion lVater-VVheels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation thereof, reference being had to the accompanying drawings, making part of this specication, in which- Figure l represents an end view, and Fig. 2 a top view of the wheel.

The letters refer to the same parts in the dierent figures.

The nature of my invention consists in attaching to and combining in a laterally discharging water wheel a series of vertical and horizontal flanges or buckets, constructed and arranged as hereinafter described, and possessing advantages over other wheels in which buckets constructed on similar principles are used, but separately and uncombined.

I construct a wheel of cast iron or other suitable material and place it on a shaft (A) with suitable bearings in a scroll case or water chutes (not shown) made in any of the usual forms. Upon the hub D I place vertical buckets B (by which I mean buckets which are perpendicular to the axis of the wheel in any of its sections in the line of said axis) approaching in a spiral form from the end of the wheel at a toward the center of its periphery, and stopping at b where also the horizont-al buckets C (by which I mean buckets which are parallel to the aXis of the wheel in any of its sections in the line of saidaxis) terminate, which gradually rise from the point e in a convex curve to the der to save expense in construction, when a high velocity is not required, leave out the portion of the wheel contained between the lines CZ, e, and f and above the level of the horizontal buckets, thus throwing two buckets into one. The space between the edges of the vertical buckets and the ends of the wheels are covered by a rim The water being admitted into the scroll case or chute presses by its weight and momentum against the surfaces of the vertical and horizontal buckets and escapes at the apertures F at the ends of the wheel.

The material advantages to be derived by using the horizontal and vertical buckets combined as before described are in the first place the prevention of the action of the portion of the water which would otherwise act upon the portions of the vert-ical buckets between the dotted lines in Fig. l and the `hub D and causing it to give out its eiective torce nearly at the periphery of the wheel, making a great gain in leverage ,1 secondly, it has a tendency to give a more .steady action and uniform motion to the wheel.

-l/Vhat I claim as my invention and desire ABEL GREENLEAF.
